Spectrofluorometer

荧光是一种重要的光物理现象，可以在各种材料中观察到，从小有机分子、无机配合物到合成聚合物、生物大分子和纳米颗粒。了解荧光性质是在分子水平上研究结构、电子和化学性质的重要而有力的方法。因此，荧光光谱技术在科学和工程研究中得到了广泛的应用。例如，可以合理设计某些荧光有机和无机化合物作为化学传感器和生物传感器，能够以超高的灵敏度和选择性识别和定量环境和生物重要的化学物种。荧光蛋白可以被引入到活细胞中来标记和跟踪生物分子。各种具有高荧光效率的有机共轭聚合物和功能化纳米颗粒可以作为有效成分应用于制造先进的发光器件（led）。诚然，荧光材料在现代科学技术中发挥着核心作用，而对这些材料的研究很大程度上依赖于先进的荧光光谱分析技术。

Fluorescence is an important photophysical phenomenon that can be observed for various materials, ranging from small organic molecules, inorganic complexes to synthetic polymers, biomacromolecules, and nanoparticles. Understanding of fluorescence properties is a vital and powerful approach to investigate structural, electronic, and chemical properties at the molecular level. As such, the technique of fluorescence spectroscopy has been extensively employed in scientific and engineering research. For example, certain fluorescent organic and inorganic compounds can be rationally designed to act as chemosensors and biosensors capable of recognizing and quantifying environmentally and biologically important chemical species with ultra-high sensitivity and selectivity. Fluorescent proteins can be introduced into living cells to label and track biomolecules. Various organic conjugated polymers and functionalized nanoparticles with high fluorescence efficiencies can be applied as active components in the fabrication of advanced light emitting devices (LEDs). Indeed, fluorescent materials have play a central role in modern science and technology, while the studies of these materials heavily reply on advanced techniques of fluorescence spectroscopic analyses. We plan to purchase a spectrofluorometer, which will be an essential research tool for investigating various fluorescence properties. At Memorial University, there are many research programs requiring an on-campus access to such equipment. In particular, researchers in the fields of materials chemistry, environmental engineering, and processing engineering require fluorescence spectroscopic measurements to advance their programs of research. Unfortunately, a fully functional spectrofluorometer is not available at Memorial University. Access to this important research tool will greatly benefit our research and HQP training programs. In the long term, the proposed spectrofluorometer will offer a technical platform to strengthen cutting-edge research programs, foster new research collaborations, and extensively train HQP in multiple disciplines.
